The immediate culprit appears to be https://go.dev/cl/416134.

cmd/go: avoid indexing GOROOT packages when the compiler is 'gccgo'
62da8d2 
The gccgo compiler does not load standard-library packages from
GOROOT/src, so we cannot load those packages from the GOROOT/src
index when using that compiler.

This fixes TestScript/gccgo_link_c (and perhaps other gccgo tests)
when a 'gccgo' executable is present. Unfortunately, only a few
builders caught the broken test because 'gccgo' is not installed
on most Go project builders (see golang#35786).

For golang#53577.
Fixes golang#53815.
